I see some micro jitters but that isn't good shooting technique for handheld, if you're determined to get a perfectly still shot, put the camera on a tripod and turn off the stabilizer. Handheld works best with more camera movement. Add weight to the rig will smooth it out too. And stay wide.

@Vesku It is the first version of 14-140 HD lens. Jump is small and rapid and aleatory. It happens on Black magic when I use a strong focal (140) but I'm on a stable monopod and I start doing very soft movement. Didn't notice such a behavior on my Gh2 or Gh3 bodys, neither with the 12-35, but I can't be more precise because I started shooting a lot on m43 not long ago.

@brianl

Thanks for your opinions and tips. I am not making films. I just take photos and videos to my and my friends needs. I can get perfectly acceptable videos handheld with MEGA OIS lenses. Why cant I get good results with POWER OIS even if I try very hard. I have steady hands and I shoot wide handheld. In fact I can get steadier shots handheld at 300mm MEGA OIS than 14mm POWER OIS. That is absurd.

Can we make list of affected lenses?

Make clear and short description of issues?

Make short and test, may be even find exact reason of issue.

And what might then happen? Are you going to do something with this issue. Maybe inform your Panasonic contacts?

Panasonic already reading your topic :-) You can be calm about it.

I just want to do formal things required in any testing.

I just want to do formal things required in any testing.

I dont exactly understand what that means? Do you need some test results?

I own a GX7 with the 14 - 140 II and have the same issue on handheld videos. MEGA OIS from my old 14-140 ( from GH2 Kit) is a lot smoother. For stills i use electronic shutter of the GX7 - because of the shutter shock . The new 14-140 II is sharper in stills and video but have the micro jittering in (handheld) video mode. Hope Panasonic can fix it with a fimware update and it is not an mechanical issue of the lens.

@Vesku Is that the original version?

To everyone: It would be helpful if we put lens title and model number (because there are now MKII and it will be sure we know which lens we're talking about) and whether you experience the issue. And, if you know, whether it is mega OIS or Power OIS.

Lens: Lumix 14-140 F4.0-5.8

Model: VS014140

OIS designation: Mega OIS

Micro Jitter Problem: None

I have told in every post that the jitter issue is in 14-140mm II (II=mk2=new version).

I saw with my own eyes the same jitter in updated 12-35mm f2.8 lens (H-HS12035 Ver.1.2)

I got a micro HDMI-cable and I tested in real time in big screen my GH4 and 14-140 II / 14-42 lenses. 14-140 II POWER OIS floats stabilation very nice. When I pan slowly and stop motion the image moves little further and stops nicely. The video image floats and lags a bit behind hand movement. When I stop movement and try to keep it steady the OIS starts to jitter image like it is too willing to go to some direction. With 14-42mm image is very steady but the movement are not floating as nicely. So POWER OIS has better floating feel but you should never stop camera motion.

I can confirm the issue on the 35-100mm after testing a friend's lens side-by-side with my 12-35mm. It is much worse and it can't really be fixed with AE's warp stabilizer, since the micro-jitters blur one or two frames and that shows even more after stabilization. The 12-35mm has minor jitters too, but considerably less.

I'll soon test an old 14-140 to compare.

I did a quick test of my 42.5mm lens and could not see any micro jitter - at least it wasn't as obvious as the micro jitter I documented on my 35-100mm F2.8 lens. I'll try to do a more formal test this weekend to compare to my previous test. I wonder if the combination of Power OIS and Zoom lens could be a factor?
